Keeping up with 375 heifers and calves, along with milking an additional 400 cows and farming 900 acres on this family farm is not an easy task. Managing that many cattle required the construction of a new 7.75-million-gallon manure pit with strict construction requirements. The new pit was built to consolidate nine existing pits into a single pit. The project started in the early fall 2017 with an aggressive pour schedule because the other pits were reaching capacity too frequently. One of the largest boom pump trucks in the state was called in to help meet the aggressive concrete pour schedule and because of its ability to reach the long stretches necessary.
Before any ready-mix was poured, the site was excavated to create the pit’s shell. Next, crews lined the pit with steel rebar for reinforcement. Sandy subgrades on the sight made maneuvering the pump truck and ready-mix trucks a challenge. The 203-foot boom on the pump truck helped minimize moving equipment because its long span could reach most of the pit perimeter. Heavy rain was also significant challenge to the construction schedule; pours were scheduled and delivered between heavy rain events.
County Materials supplied the entire 150,000 sq. ft. pit, which was completed in only six pours. Each pour was made up of an impressive 750 cubic yards of ready-mix. Crews ran drainage pipes underground to the pit, then poured ready-mix around them. The pipes protrude into the pit for handling leachate drainage from nearby silage storage. As the ready-mix cured, crews operated a laser screed on the flat bottom surface and rolled the surrounding slopes to create texture needed for increased traction.
